Speccaton of Lettersflatent No. 10,826, dated .April 25, 1854.

To all whom t may concern;

Be it known that we, GEORGEC. JONES, of

Alna, and PETER KTNG, of Wvhitefield, in thev county of Lincoln,State of Maine, have invented a new and improved machine for shaving or forming wedges for' wedging treenails to be used for shipbuilding, wedges for sashes or other mechanical purposes, shaving shingles, or making any other wedge forms of wood; and we hereby declare thatthe following is a full and exact description thereof, reference being had to the accompanying drawings.

Figure l represents a view of the back side of the framework of the machine. A, A, A, A, A is the wood or framework. B, B, B, are slots oropenings in which parts of the machine play. C, represents a spring. S, shows one of the guides of the cutter or shave.

Fig. 2 represents the spring C more fully. P is a plate projecting at right angles to the body of C, which is made to pass back and forward. It holds the wood in its place while being shaved and then is pushed back by a projection of the chisel or shaver when the shaving is done and lets the wedge fall out.

Fig. 3 represents the cutter, chisel or shave. rlhis is made of steel and is strong and of good cutting timber. D, is the blade. E, E, are arms by which it is made to slide up and down while shaving, being fitted to the guides S, S. F is the head of the chisel, fitted with a slot, into which is pinned a lever or handle by which the chisel or shave is worked up and down. This head is at-` tached to the v'chisel by a pivot or joint, which enables it to accommodate itself to the lever as it is worked up and down. G, is a narrow chisel affixed to the face of D, and standing out at right angles to its face. This is used for straightening or shaving one edge of the wedge. H, is another similar chisel affixed in the same manner to straighten and smooth the other edge of the wedge. This chisel has a rounded hump or projection, the office of which 1s to come in contact with the projection P, of the spring C, when the cut has gone through the wedge and pushing it back allows the wedge to fall out for want of support.

`.their points. Y 1s here meant the distance the bottomor grooves are sunk into the wood or framework of the machine for receiving the blocks of wood prepared for shaving, and itis the shape or construction of the bottom or ioors of these grooves that gives form `to the Wedges as regards their thickness at the butts and points. The thickness of the butt end ofthe wedge is regulated by the depth ofthat end of the grooves next the chisel orA shaver, and raising or elevating these bottoms or floors at the other ends gives form to the wedge and any desirable thickness at Bythe depth of the grooves fioor of the groove is from the face edge of the chisel or shaver.4 Then the wedge is required to be thicker at the butts the bottom or floor of the groove is to be sunk down so as to give it greater dept-h from the face edge of the chisel. Then required to be thin at the butts the floor is to be raised up nearer to the face edge of the chisel so that by sinking or raising the floors of t-he grooves and otherwise enlarging or diminishing them in length and width, the chisel being enlarged or diminished in proportion, wedges of any dimensions and forms can be made by the machine. The openings through the wood work on the right hand side of the grooves are for the purpose of letting the chips or shavings made by the narrow chisels G and H, for shaving the edges of the wedges, to

fall through under the machine, as well as giving space for these narrow chisels to play in. All the references in this iiOure refer to the same parts as in the other figures. But the machine is here exhibited in a front view. Although the figures here represent the machine standing upright on one end, yet when in operation it is laid horizontally on a bench and the chisel or shaver worked hori- Zontally.

The grooves for making treenail wedges are thus constructed: The first or left hand tier for forming one-half of the wedge are 2g or 3 inches long, as convenience may require, 11% inches wide at the end next the chisel, forming thev butt of the wedge, and l inches at the end forming the point of the wedge, their depth next the chisel fg inch and at the end forming the point of the wedge 57g inch. The second or right hand tier of grooves for finishing the wedges are of similar length with the iirst, their width at the end next the chisel l inches and at the end forming the point of the Wedge l inches, their depth at the end neXt the chisel forming the butt of the Wedge inch and at the end forming the point of the Wedge 51g inch. The Widths here given are the dis tances between the cutting edge of the narrovv chisels used for edging the Wedges and the shoulder on right hand side of the grooves. Gages are inserted against the shoulders on the right-hand side of the grooves to give the Wedge any Width or forni required.'

`Mode of operation: The slots or grooves are Inade of any required length. The Wood to be shaved is sawed and split into the right dimensions, is then put into the left hand tier of grooves as the machine lies on its bearings and the chisel brought down. This motion shaves one side and one edge of the Wood thus put in, forming one-half of the Wedge. They are then taken out turned over into the other grooves, the chisel brought down again, When the lother side and edge is formed by the operation and the Wedge linished.

lhat We specially claim as our invention and for which We ask an exclusive right is- 1. yVle claiin the peculiar form of the chisel having tWo or more projecting chisels at right angles to the face of the main chisel and an appendage for pushing back the spring C, as above described.

2. The application of the spring C, and its projections P, for t-he support of the Wedge While being shaved as before described.

8. The peculiar form and arrangement of Y GEORGE C. JONES. PETER KING.
